Because if you did, let me respond to you... [turns off tape recorder] Let me respond to you this way. I'm an officer, and therefore, by proclamation, a gentleman, but don't abuse that, son. Don't get in my crosshairs, because I'll have no compunction whatsoever about getting up to my neck in yo' ass. Do you understand me?"
